As with most survey research, the respondents provide individual opinions at a single
point of time. With efforts made to qualify respondents, we assume the validity of the results;
but recognize that future research from a longitudinal perspective would also be beneficial.
Analyzing moderators on uncertainty / collaboration relationships is a means for establishing the
how and why of these links. Identifying additional moderators to these relationships would be
valuable. For example, looking at transaction frequency on the behavioral uncertainty supply
chain collaboration relationship may be useful. Transaction frequency would assume that a high
level of transactions may actually lessen the relationship between behavioral uncertainty and
supply chain collaboration. This could be due to the speed with which partners will become
familiar with one another implying that knowledge gained of each other’s processes will happen
quickly. Additionally fully assessing the impact of the number of suppliers on the behavioral
uncertainty / collaboration link would be helpful. Determining if the number of suppliers from a
numbers perspective or whether just having a defined opportunity set is the reason for the impact
on the relationship deserves further attention.
